Diagnosis Procedure

SYMPTOM 1: 

• Selector lever cannot be moved from "P" position with ignition switch in ON position and brake pedal depressed. 
• Selector lever can be moved from "P" position with ignition key in ON position and brake pedal released. 
• Selector lever can be moved from "P" position when ignition switch is removed from key cylinder. 

SYMPTOM 2: 

• Ignition key cannot be removed when selector lever is set to "P" position. 
• Ignition key can be removed when selector lever is set to any position except "P" position. 

1. CHECK KEY INTERLOCK CABLE

   Check key interlock cable for damage.

   OK or NG 

   OK: GO TO 2.

   NG: Repair key interlock cable. Refer to "REMOVAL AND INSTALLATION ".

2. CHECK A/T POSITION

   Check A/T position. Refer to "CHECKING OF A/T POSITION ".

   OK or NG 

   OK: GO TO 3.

   NG: Adjust control cable. Refer to "ADJUSTMENT OF A/T POSITION ".

3. CHECK SHIFT LOCK SOLENOID AND PARK POSITION SWITCH
   1. Turn ignition switch ON. (Do not start engine.)
   2. Selector lever is set in "P" position.
   3. Check operation sound.
      BRAKE PEDAL OPERATION
      
      

      Condition	Brake pedal	Operation sound
      When ignition switch is turned to ON position and selector lever is set in "P" position.	Depressed	Yes
      	Released	No

      OK or NG 

      OK: INSPECTION END 

      NG - 1: With intelligent key: GO TO 4.

      NG - 2: Without intelligent key: GO TO  5.

4. CHECK POWER SOURCE
   1. Turn ignition switch ON. (Do not start engine.)
   2. Check voltage between A/T shift selector harness connector terminal 5 and ground.

      Voltage: 

      Brake pedal depressed: Battery voltage 

      Brake pedal released: 0V
